First I assume you only used internal flash
Anyhow, if it is internal flash only, unless the water is crystal clear, I think you pretty much stuck with macro shots otherwise you are going to have a lot of backscatter regardless of what camera you use. You will get much better result when you shoot something that is no more than 1-2 feet away.
Underwater photography is going take awhile before you get comfortable with all the settings and know when and where to take the pictures.
Like Clive Francis say, digital camera learning curve is a bit faster as you get instant feedback so you know what to adjust but it is not impossible to learn to shoot with 35mm, just more films and practice.
